Sayaguesa

Cattle

The Sayaguesa Cattle, also called Zamorana Cattle, is an ancient, aurochs-like cattle breed from Sayago in the province of Zamora in the Spanish autonomous community of Castile and León. Sayaguesa are rather large, with bulls weighting between 1000 and 1100 kg and cows 650 and 700 kg. The bulls are black and often have a black eel stripe. The cows often are only slightly lighter than the bulls,but there are some wild type coloured brown Sayaguesa cows left.
